How can i make a UIPickerView that appears when i select a TextField, and the input of this comes into TextField if i select a value of UIPickerView?
How to do this? Have you an example of this?
Create the UIPickerView and set it as the inputView of your text field. It will then be animated on screen for you when you start editing the text field. The picker view delegate methods can be used to update the text field's value.
You will also want to create a toolbar with a done button and set this as the inputAccessoryView - this will allow you to dismiss the picker when you have selected your value. Again, this will appear automatically above the picker view when the text field begins editing.
Please take a look at this example http://www.techotopia.com/index.php/An_iOS_4_iPhone_UIPickerView_Example
You can initially hide the picker by
picker.hidden=YES; in your viewdidload method and for showing it when touch on the textfield you can write picker.hidden=NO; inside uitextfielddidstartediting method. Thanks.

I have a NSTextField and Label whose value is bind to same NSString in the view Controller
The problem here is the label only gets updated when I press Tab.
How do I make it continuous, so that what ever I type in the text box gets reflected in the label immediately?
As of now I am using -(void)controlTextDidChange:(NSNotification *)obj; selector, but I am expecting a binding only solution.
Select the relevant NSTextField in Interface Builder, then navigate to the Bindings Inspector. You need to make sure Continuously Updates Value is checked:
Wheres the custom picker element for monotouch dialog (Xamarin.IOS)?
// update
UIPickerView would be a wonderful element to have as a monotouch dialog element along with UIActionSheet.
Instead I journeyed into building one by hand and then attempted to fit it into an UIActionSheet. Was couple of days work (I'm a noob) but got stuck trying to clean up the aesthetics of it (think I'll just stick with a 'ok' solution of embedding the picker inside a table for now).
Just in case anyone else embarks on this adventure here's a link to make your picker:

Although not a custom picker element using MT.D, you can sort of have a popup picker by linking the input view of a control (view object i.e. text field) and set it's input view property to the picker. The picker slides in from bottom whenever you click this control. Think I just have to implement a custom view with my own picker and a cancel button somewhere...hmmmm:

Your update is correct - you'll want to create a custom MT.D element that inherits from EntryElement, override the method that creates the UITextField and set the field's InputView to an input view of your choice. I actually just wrote a tutorial on this: Custom MT.D Input View & Element
I'm working on an app that presents an NSPopover containing a number of NSTextFields. While I can tab between these fields as I expect, the popover is selecting a particular text field to be in the editing state when it appears, and it's not the field I want to edit; I'd like to be able to define which text field is editing on popover appearance programmatically (or in Interface Builder). How can I do this?
I've set up the appropriate key view loop by connecting IB outlets for all the various text fields involved, and I've hooked up the popover's nextResponder property to the text field I want to edit first, but that doesn't seem to have an effect - the popover will still select its preferred text field instead of mine. The Window Programming Guide suggests that I set the initialFirstResponder outlet of the window to the view I want selected, but an NSPopover is not an NSWindow and has no initialFirstResponder property (unless I'm missing something obvious).
Is there any way to specify which NSTextField I want to be editing when an NSPopover appears?
I think you said you tried using -makeFirstResponder: and passing the text field. This will set the window's firstResponder, but that's not the same as initialFirstResponder and the window must have initialFirstResponder set to something other than nil in order to respect the key view loop. (Source) A slight tweak to what you tried worked for me:
- (void)popoverWillShow:(NSNotification *)notification
{
// Set the window's initialFirstResponder so that the key view loop isn't auto-recalculated.
[[myField window] setInitialFirstResponder:myField];
}
I think you can make this work by setting all the text field's that you don't want to have focus to "selectable" instead of "Editable" in IB, this should leave the one text field you want to start with as the first responder. Then, in your popoverDidShow: method, set them all back to editable, and you should be able to tab between them as usual.
Right now I am just using a NSTextCell with a NSDateFormatter, I just wanted to know if this was possible, perhaps by using the .
Thanks in advance!
not without making a bunch of hacking... Apple doesn't provide the date picker cell for the table for some reason. I would keep the date formatter or make it so when the cell is clicked, it pops open the graphical date picker.
I created a menu in the xib file, set the outlet for the cell's menu property to the menu, created a subclass of nsdatepicker, overrode the mouseDown:, and made it display the menu when clicked.
I need to display/show a Picker when a user taps on a textfield, I mean, it should appear a picker instead of a keyboard. Also, some sort of "done" button above the picker so the user clicks on it and the value from the picker is copied to the textfield and the picker is hidden again.
I've checked many tutorials from the web but haven't found anyone that can really help me.
I found a tutorial that pointed me in the right direction but I'm still missing to disappear the keyboard when clicking on the textfield.
Dismissing UIPickerView with Done button on UIToolBar by #slev
Any ideas?
If you're not targeting iOS versions older than 3.2, it's easy. You can either assign the UIPickerView as the inputView property of the UITextField and the UIToolbar containing the 'done' button as the inputAccessoryView, or you could make a single UIView that has both the picker and the toolbar as subviews and assign that as the intputView (and leave inputAccessoryView as nil). Either way, this will animate your picker in in place of the normal keyboard when the text field is activated.
More details on this are available in the documentation.
